Abstract (en)
An apparatus control method forms hidden image information comprising hidden information related to control instruction of a controlled apparatus and forms composite image information (12) by embedding the formed hidden image information in the invisible state against the main image information. The formed composite image information is recorded on a recording medium (P) and the composite image information is read (13) from the recording medium (P) that records the composite image information (12). The hidden information is restored (21) by extracting hidden image information from the read composite image information and control instruction is decoded (22) from the restored hidden information and a controlled apparatus (15) is controlled by executing (24) the decoded control instruction. <IMAGE>
